This structure is used to hold a retrieved USB-defined device descriptor. This information can then be used to further configure or retrieve information about the device. Device descriptors are retrieved by submitting a get-descriptor URB.
The iManufacturer, iProduct, and iSerialNumber values, when returned from the host controller driver, contain index values into an array of string descriptors maintained by the device. To retrieve these strings, a string descriptor request can be sent to the device using these index values.
